Choosing a sunglasses manufacturer by unit price alone creates expensive problems later. The real cost appears in unstable color, loose hinges, delayed cartons, rejected inspections, or inventory that cannot be sold in the target market.
MOQ, lead time, and quality control shape cash flow, launch timing, return rates, and brand reputation. A two week delay can miss a summer campaign. A lens that looks acceptable on a desk may show distortion outdoors.
A useful quotation starts with a clear product brief. Define the target market and expected retail price, then specify the frame material: acetate, metal, TR90, or injection molded plastic. Add the lens type—polarized, UV400, mirrored, gradient, or another required option.
Frame dimensions, colors, surface finish, logo position, branding method, packaging, and accessories should also be included. Photos help, but dimensions and material callouts help more. “Similar to this image” leaves too much room for interpretation.
Packaging is often treated as a late decision. It should not be. A custom hard case can affect carton size, shipping cost, and assembly time.
Confirm whether the supplier is an actual factory or a trading company. Either can be useful, but the buyer should know who controls production and who is only coordinating it.
Ask which operations are handled in house: design, sampling, mold development, production, assembly, packaging, and export documentation. Request recent factory audits, test reports, and relevant certifications.
A capable factory should explain its production flow clearly. If it cannot say where plating, lens cutting, or testing occurs, control may be weaker than the sales presentation suggests.
MOQ changes with the level of customization. It may also apply by model, color, lens option, or logo—not only to the total purchase order.
| Order Type | Typical Commitment | Best For |
| Ready stock styles | Lowest MOQ | Market testing |
| Stock frames with logo | Low to medium MOQ | Startups and private labels |
| Modified existing designs | Medium MOQ | Growing brands |
| Fully custom OEM designs | Highest MOQ | Established or differentiated brands |
SUSON can support a minimum MOQ of 20 units for suitable programs. A stock frame order is very different from 20 pieces requiring a new mold, custom plating, and bespoke packaging.
Compare the MOQ at SKU level. A supplier quoting 300 pieces may mean 300 per color, turning a three color launch into 900 pieces. That single detail changes the cash flow calculation immediately.
Do not accept one broad statement such as “30 days.” Ask the supplier to separate design and specification confirmation, mold or tooling development, material procurement, production, final inspection and packaging, and shipping transit time.
Define when the clock starts: deposit, sample approval, artwork approval, or material arrival. Factories are sometimes waiting while buyers assume production has started.
Complex customization, repeated revisions, custom molds, material shortages, special packaging, and peak seasons can all move the date. A late change from a smoke lens to a custom gradient may require another sample and approval round.
Build a small buffer around major retail dates. Occhiali da sole delivered two days after a campaign launch are not “almost on time.” They are late.
Quality cannot be inspected into a product only at the end. The factory needs written checkpoints, acceptance criteria, records, and a method for handling defects.
Incoming inspection should cover frames, lenses, hinges, and other components. Checks should follow molding, polishing, painting or plating, lens fitting, and assembly. Lens alignment and optical performance need dedicated checks. Before packing, use final sampling or 100% inspection as agreed.
Defects often cluster. One loose temple may be random; six from the same line suggest a process issue. Records should make that pattern visible.
Confirm requirements for UV protection, lens category, impact resistance, labeling, and any applicable ANSI, ISO, CE, FDA, or destination market rules. These terms are not interchangeable, and a generic “CE certificate” is not enough evidence for every market.
Ask for reports matching the material, lens type, and model where possible. Confirm who pays for third party testing and what happens after a failure.
Put every quotation into the same comparison sheet. Review MOQ flexibility, sample cost and timing, unit prices at several quantities, production and delivery time, frame and lens specifications, QC procedures, testing support, and included packaging.
Normalize the details before judging price. One quote may include polarized lenses, a case, cloth, labels, and inspection; another may cover only the frame and basic lens.
Communication deserves a column too. A supplier that catches a conflicting dimension before sampling offers more value than one that says yes to everything.
The purchase order should reflect the approved product, not an earlier quotation or an informal chat. Any open point can become a dispute once production begins.
Keep an approved or sealed reference sample. Names such as “tortoise brown” are too subjective; a controlled reference settles disputes faster.
The right manufacturer balances MOQ, lead time, quality, compliance, and communication. The lowest quote may still be the wrong fit. So may a technically strong factory whose minimum order ties up too much cash.
A trial order reveals how the supplier handles drawings, revisions, inspections, and deadlines. Scale after the process works. Send SUSON the design, target quantity, market, and delivery date for a tailored proposal and quotation.
Domanda: What is a reasonable MOQ for custom sunglasses?
Ready stock frames with a logo may start low, while new molds and custom materials require a larger commitment. SUSON can offer an MOQ from 20 units for eligible projects.
Domanda: How long does OEM sunglasses production take?
Stock based orders may move quickly. Custom projects take longer because tooling, sourcing, sampling, testing, and approvals precede production. Ask for a milestone schedule.
Domanda: Should a buyer arrange a third party inspection?
For a new supplier, a high value order, or a strict launch deadline, third party inspection is usually a sensible cost. The inspection standard and defect limits should be agreed before production.
Domanda: Is a test report enough to prove compliance?
Only when the report is relevant to the actual product and destination market. Check the model, materials, lens specifications, test method, laboratory, and report date. When in doubt, request product specific testing.
